Head—body 69-80 mm, tail 12-26 mm, hindfoot 10-13 mm; weight 5-13 g. The Southern Short-tailed Shrew is large and robust, but it is significantly smaller than the Northern Short-tailed Shrew (B. brevicaudus) and Elliot’s Short-tailed Shrew (B. hulophaga). There seems to be a clinal increase in size from south to north in western populations. Pelage is short, soft, velvety, and mole-like. Dorsal pelage is slate grayish black or brown, with silvery tinge; ventral pelage is slightly paler. There is a bare patch of lightly colored skin around diminutive eyes. Ears are very small and completely concealed by fur; vibrissae are long and white. Tail is less than 30% of head-body length, hairy, and similar in color to dorsal pelage, with small tuft at end. Feet are short and broad, with long claws, and are paler than rest of body. Hindfeet are darker than forefeet. Females have three pairs of inguinal mammae. Characteristic of the genus, the Northern Short-tailed Shrew has five unicuspid teeth and significantly larger and angular skull than other shrews. All species of

also have reddish teeth from iron deposits within their teeth. They can be differentiated from the Northern Short-tailed Shrew by height of the coronoid process, which is typically less than 6 mm, and length of mandibular tooth row, which is usually less than 6-5 mm. Southern Short-tailed Shrews might also have venomous saliva similar to the Northern Short-tailed Shrew. More than 89 species of parasites have been recorded from the Southern Short-tailed Shrew, including cestodes (Cryptocotylepis), trematodes (Brachylaima, Brachylecithum, and Panopistus), nematodes (Capillaria, Longistriata, Physaloptera, and Porrocaecum), thorny headed worms (Centrorhynchus), mites (Androlaelaps, Asiochirus, Bakerdania, Blarinobia, Comatacarus, Cyrtolaelaps, Euschoengastia, Glycyphagus, Protolaelaps, Prowichmannia, Xenoryctes, etc.) fleas (Ctenophthalmus, Doratopsylla, and Stenoponia), ticks (Dermacentor), and beetles (Leptinus). Chromosomal complement has 2n = 46 and FN = 44-45, but it was reported to be 2n = 31-41 and FN = 41-45 in western Tennessee and northern Mississippi.

Variety of moist and upland habitats such as moist deciduous woods, brushy areas, pine woodland and forest, mixed oak/pine/juniper woods, grassy regions, and densely wooded floodplains. Southern Short-tailed Shrews can also be found in disturbed habitats such as strip-mined regions, abandoned agricultural fields, and areas disturbed by tornadoes. They are most commonly found in moist environments, with deep leaflitter and rotting logs in which they regularly build nests, but they can be abundant in dry habitats in some regions.

and related genera; 16-3%), earthworms (14-8%), beetles (9-6%), and beetle larvae (5-8%) in upper coastal plain of South Carolina. In xeric pine forests of North Carolina, they ate centipedes (22-:3%), hypogeous fungi (14:6%), fly larvae (12:3%), spiders (10%), and flies (9-1%). In Tennessee, beetles, ants, and slugs were most abundantin the diet. On Cumberland Island off the coast of Georgia, they ate introduced terrestrial amphipods (7Talitroides topitotum; 21-8%), beetle larvae (12-4%), centipedes (11:8%), earthworms (9-1%), moth larvae (8:6%), and spiders (7-4%), and fungi made up only 3-:8% of the diet. They might eat small amounts of plant material and small mammals, but there are no reports of this. Although venom and hoarding has not been recorded, they might have a venom similar to the Northern Short-tailed Shrew, which is used to subdue prey and potentially hoard paralyzed prey.

Breeding of the Southern Short-tailed Shrew occurs from February or March to November in most of its distribution, but a lactating female was captured in southwestern Alabama in late December, indicating a longer and possibly year-round breeding season at southern latitudes. There are peaks in reproductive activity in spring and late summer/early autumn. Gestation probably lasts 21-30 days. Litters have 2-6 young (average c.3-9) across its distribution, but averages of 3-7 young in March—July and 4-2 young in September—November in South Carolina have been reported. Southern Shorttailed Shrews can breed multiple times each season and after c.60 days of age; young born early in the season can breed in the same year they were born.

Southern Short-tailed Shrews are semi-fossorial and primarily nocturnal. They are captured more frequently at night in summer and during the day in winter, probably due to cooler temperatures at night in summer and warmer temperatures during day in winter. They build extensive tunnels in topsoil and deep leaflitter. Nests are built 30 cm belowground under logs or even within rotting logs. Nests usually are filled with roots and grass.

The Southern Short-tailed Shrew is solitary except when breeding and rearing young. Population size and abundance fluctuate among seasons and years, peaking following spring and autumn when reproductive activity is at its highest. In southern Illinois, densities peaked at 57 ind/ha in late summer and early autumn, gradually decreasing in winter, and rate of capture was higher with increased humidity and decreased precipitation. Densities in South Carolina were 1-2-2-2 ind/ha in winter and early spring and 6-3 ind/ha in late summer and early autumn—all of which are significantly smaller estimates than those found in southern Illinois. In South Carolina, home ranges of seven individuals averaged 0-96 ha.

Classified as Least Concern on The IUCN Red List. The Southern Short-tailed Shrew is common and widespread with no major threats. Densities can be affected by drought and habitat destruction, but they are generally considered resilient in disturbed habitats.
